A laser scanning lens is an optical lens that uses a laser beam to scan. It is usually used in laser equipment such as laser scanning microscopes, laser printers, and laser cutting machines. 1. Working principle of laser scanning lens The working principle of the laser scanning lens deeply integrates optical principles and precise control systems, which work together to achieve high-precision focusing and scanning of the laser beam on the target, and realize high-speed, high-resolution scanning and processing capabilities. Laser scanning lenses use a combination of laser beams and scanning lenses to achieve accurate three-dimensional measurement and scanning. The following is a detailed explanation of the working principle of laser scanning lenses: (1)C ontrol system The precise operation of the laser scanning lens is inseparable from an efficient control system. The system integrates components such as drives, encoders, and advanced control software to accurately control reflective e...

IR corrected  lenses usually include infrared lights and low-light compensation technology, which can adapt to different lighting environments and effectively monitor road traffic conditions under different lighting conditions during the day and at night to ensure road safety and smooth traffic. Therefore,   IR corrected  lenses have important application value in road monitoring. Specific applications of IR corrected  lenses in road monitoring 1. Daytime monitoring Under conditions of sufficient daylight, the IR corrected  lens can capture vehicles, pedestrians and other traffic conditions on the road using high definition and intelligent focus functions, and provide clear images and videos to achieve real-time monitoring of road traffic conditions, vehicle driving status, traffic violations, etc. It can capture clear license plate numbers and driving trajectories, which is conducive to traffic management departments to capture and record violations. IR correc...

CCTV  lenses , that is, CCTV  camera lenses, have more and more application scenarios today. It can be said that CCTV  cameras are needed wherever there are people and things. In addition to being a security management tool, CCTV  cameras are also used in crime prevention, emergency response, environmental monitoring and other applications, and their role cannot be underestimated. 1. How do CCTV  lenses work? For CCTV  lenses, we can look at its workflow: (1) Capturing images The CCTV  camera captures images of the target area through image sensors and converts them into electrical signals. (2) Processing images The image signal is transmitted to the internal image processor, which then performs automatic exposure adjustment, white balance correction, noise filtering and other operations to optimize image quality. Common CCTV len s (3) Data transmission The processed image data is transmitted to the storage device or monitoring system through a data tr...

The wide-angle lens is one of the commonly used lens types in landscape photography. It is widely used in landscape photography and can help photographers capture wider scenery and create landscape works with grandeur and profound significance. Wide-angle lenses are widely used in landscape photography Specific applications of wide-angle lenses in landscape photography In landscape photography, using a wide-angle lens can show magnificent natural scenery and urban landscapes, making the work more colorful. Let’s take a look at the specific applications of wide-angle lenses in landscape photography: 1. Shooting wide-ranging scenes Wide-angle lenses are suitable for shooting vast natural scenery, such as the sea, mountains, grasslands and other vast natural scenes. It can help photographers present the vast scenery as much as possible in the picture, creating an open and layered picture, allowing the audience to feel the grand momentum. 2. Intake of more visual elements A wide-angle len...

In the field of industrial automation, cameras and lenses are important components for visual inspection and identification. As the front-end device of the camera, the lens has a crucial impact on the final image quality of the camera. Different lens types and parameter settings will have a direct impact on the image clarity, depth of field, resolution, etc. Therefore, choosing a lens suitable for industrial cameras is the basis for achieving high-quality visual inspection. 1. Classification of industrial camera lenses Professional industrial camera lenses can be divided into the following categories: (1) Fixed focus lens Fixed focus lens is the most commonly used lens type in industrial cameras. It has only one focal length and a fixed shooting range. It is suitable for determining the distance and size of the detection target. By adjusting the shooting distance, different sizes of shooting ranges can be achieved. (2) Telecentric lens Telecentric lens is a special type of industrial ...

As one type of optical filter , double-pass filter (also known as transmission filter) is an optical device that can selectively transmit or reflect light in a specific wavelength range. It is usually stacked by two or more thin film layers, each with specific optical properties. It has high transmittance within two specific wavelength bands, and has blocking properties in other wavelength bands between these two bands. 1. Working principle   of double-pass filters The working principle of double-pass filter is mainly based on the interference effect of multi-layer film. When light enters the filter, it interferes between different film layers. By designing and controlling the thickness and refractive index of the film layer, it is possible to selectively transmit or reflect light of a specific wavelength. Specifically, when the wavelength of the incident light matches the wavelength used by the filter design, the light of the same wavelength will be enhanced inside the filter thro...

The focal length of a fixed focus lens is fixed and cannot be changed. It usually has a larger aperture and higher optical quality, and is suitable for taking some high-quality pictures. So, in photography and videography, are there any tips for focusing with a fixed focus lens? What are the focusing techniques for fixed focus lenses? When using a fixed   focus lens in photography, correct focusing techniques are essential to help you ensure the clarity and image quality of your still life works. Let's take a look at some common focusing techniques: Focus point selection Fixed   focus lenses require a higher degree of focus accuracy, so make sure you choose the right focus point when shooting. According to the composition of still life works, you need to focus on the key parts of the subject, such as the eyes and face, to ensure the clarity of the subject. U s e  manual focus Fixed   focus lenses usually have precise manual focus functions. When shooting, you can g...
